Prison is not some magical place where you cannot die. People die in prison regularly. They die from the same causes as people who are not in prison. People in prison tend to have worse health with most giving no thought to healthy diets and exercise.
THE LIFE EXPECTANCY gap between Aboriginal and Torres Strait Islanders and the rest of the population remains two decades wide.
In all likelihood, the respite from drugs and alcohol gives many prisoners the opportunity to adopt healthier lifestyles. Unfortunately, it's an opportunity rarely taken.
If you don't want to die in custody, don't go to prison.
